Twitter’s video sharing app, Vine, has been overshadowed by the addition of video to Instagram, but that hasn’t stopped millions of people from signing up for Vine. Vine announced this afternoon that it just hit 40 million registered users today — a huge jump from the 13 million users it announced in June.

The launch of Vine’s Android app in June is likely one of the main contributors to the recent boost, but Twitter hasn’t said how many of its users are on Android, or how are even active., but with amazing videos like this, it looks like Vine might be hard to kill.
